NEW DELHI: Chennai Petroleum Corp Ltd <CHPC.NS> shut its 210,000 barrels per day (bpd) Manali refinery on Wednesday night due to heavy flooding in the southern state of Tamil Nadu, sending its shares down as much as 5 percent to a week-low.
The state-run company, a unit of the country's biggest refiner Indian Oil Corp <IOC.NS>, is the main fuel supplier to the city of Chennai that has been submerged by the strongest spell of rain in more than a century.
"We have shut down the entire refinery from last night due to heavy rains and floods," Chennai Petroleum Managing Director Gautam Roy told Reuters on Thursday in a short telephone conversation.
The company's smaller 20,000 bpd Nagapattinam refinery was, however, operating normally, he said.
Chennai Petroleum's shares were down 4 percent at 194 rupees ($2.91) in afternoon trade on Thursday. They earlier hit a low of 191.60 rupees.
India's weather office has predicted more rains in Tamil Nadu this week, which could prolong the Manali refinery shutdown and disrupt fuel supplies.
